4 questions not showing in first collapsing section

I have 10 collapsing sections, each containing questions and each with buttons visible.

For some reason the last 4 of the 17 questions in the first section collapse refuse to show. All of the invisible questions are set to show by default and there are no conditions affecting their visibility.

Have I exceeded some sort of limit for the number of questions in a section collapse?

I have attached some screenshots, but really only illustrate the lack of the 4 last questions in the 1st section collapse.

Any ideas?

My screenshots are not very helpful.

Here is a link to the form

I have checked your form and I can indeed see there are some conditions related to those fields, here's a screenshot about what I can see on my end: 

If you need the fields to be always displayed, you will need to disable or delete them. 

Hope this helps.

Thank you very much. I cannot believe that I forgot that those conditions were still in force.

Problem solved. Many thanks
